  • Juriel wants to send text messages with a BCC, and is wondering if there's a way to do that. Leo says he doesn't think so. He can always just copy and paste. There's group SMS messaging, but it won't be blind carbon copy. There are apps like WhatsApp, but the recipient would have to have the same app to use it.
  • Making use of the carbon copy (Cc) and blind carbon copy (Bcc) fields is both important and efficient. If you’re sending emails to groups of people, it’s often good etiquette to use the Bcc so.

Carbon paper (originally carbonic paper) was originally paper coated on one side with a layer of a loosely bound dry ink or pigmented coating, bound with wax, used for making one or more copies simultaneously with the creation of an original document when using a typewriter or a ballpoint pen. The manufacture of carbon paper was formerly the largest consumer of montan wax. In 1954 the Columbia Ribbon & Carbon Manufacturing Company filed a patent for what became known in the trade as solvent carbon paper: the coating was changed from wax-based to polymer-based. The manufacturing process changed from a hot-melt method to a solvent-applied coating or set of coatings. It was then possible to use polyester or other plastic film as a substrate, instead of paper, although the name remained carbon paper.[1]

History[edit]

In 1801, Pellegrino Turri, an Italian inventor, invented carbon paper to provide the ink for his mechanical typing machine, one of the first typewriters.[2]Ralph Wedgwood obtained the first patent for carbon paper in 1806.[3]

Carbon paper was the principal medium of reproduction for samizdat, a publication method used in the former Soviet Union in order to publish books without having to use state-controlled printing houses and risk the censorship or imprisonment that was commonplace at the time.

While the use of carbon paper has declined to almost nothing, a legacy of its once widespread use has remained in the header of emails, where the abbreviation 'cc' stands for 'carbon copies', the copies intended for recipients other than the principal addressee.

Fuel cell application[edit]

Carbon paper is also used in fuel cell applications. However, this carbon paper has nothing to do with the carbon paper used for copying texts. It consists of carbon microfibers manufactured into flat sheets. It is used to help as an electrode that facilitates diffusion of reagents across the catalyst layered membrane portion of membrane electrode assembly.[4]

Other uses[edit]

The advent of word-processing and the decline of typewriting meant that any number of copies of a document could be printed on demand, and the decline of carbon paper, which had already been partially superseded by photocopying and carbonless copy paper, became irrevocable. A few specialist or remnant uses remain. Examples of these are receipts at point of sale (though they have mostly been relegated to being backups for when electronic POS devices fail) or for on-the-spot fine notices, duplicate checks, and some money orders (though the United States Postal Service has recently[when?] converted to an electronic format), and tracking slips for various expedited mail services requiring multiple copies. In India, form-filling is on a sufficient scale that carbon paper is still widely used.[5] As of 2013, in Canada only one eight-person company still manufactures carbon paper, in the United Kingdom one company and in the United States only two small companies.[6][7]

There have been some experimental uses of carbon paper in art (as a surface for painting) and mail art (to decorate envelopes). Carbon paper is commonly used to transfer patterns onto glass in the creation of stained glass .[8]

Carbon paper disks are still used in school physics labs as parts of experiments on projectile motion or position, velocity, and acceleration.[9]

Carbon Copy Cloner is a popular software that lets Mac users easily back up entire disks and partitions on macOS. As macOS Big Sur is about to be released to the public, the developers behind Carbon Copy Cloner have now alerted their users about potential compatibility issues with the latest version of Apple’s operating system.

App

With Carbon Copy Cloner, users can create advanced backups of a Mac hard drive while still keeping it functional and bootable, which is great to ensure you’ll never lose your data. However, macOS Big Sur brings fundamental changes to the way the Mac manages its volumes, and this impacts software like the Carbon Copy Cloner.

Carbon Copy Approach

One of the main under the hood features introduced with macOS Big Sur is a new protection layer called “Signed System Volume” that seals and encrypts the volume in which macOS is installed. Third-party tools can still make backups of the Mac’s internal storage, but they’re not bootable and some things become inaccessible.

The system now resides on a “Signed System Volume”. This volume is cryptographically sealed, and that seal can only be applied by Apple; ordinary copies of the System volume are non-bootable without Apple’s seal. To create a functional copy of the macOS 11 System volume, we have to use an Apple tool to copy the system, or install macOS onto the backup.

Carbon Copy Application

The latest version available of Carbon Copy Cloner (5.1.22) works with macOS Big Sur, but it’s only capable of creating copies of the system volume that are not bootable. The developers responsible for the software have claimed that Apple is aware of this limitation and is currently working to resolve it.

Until then, if you really depend on macOS bootable backups generated by Carbon Copy Cloner, you might want to avoid installing macOS Big Sur once Apple releases it for all users.

Apple hasn’t announced when macOS Big Sur will be officially available to the public, but the company will hold a special event focused on Macs next Tuesday — so the launch date is probably close.
